C-51 is not predicated on evidence. It's predicated on fear, and that fear is based on media and political coverage, not silly things like numbers and facts. For C-51 they really strongly played up a "terrorist" attack on the Canadian Parliament that resulted in a single military casualty and a subsequent shootout. This single incident has been played up almost like some kind of Canadian 9/11 attack - but the reality of it is a lot less interesting - just some disillusioned youth with a gun that got up close to an unarmed solider, then got stopped by trained security forces.
